S7014 ACB/P4ADGA Bearing Product Overview & Core Advantages
The S7014 ACB/P4ADGA is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As a universal matchable (SU) bearing supplied in a pre-set duplex pair, it delivers superior performance in handling combined radial and axial loads from both directions. Manufactured to the stringent P4A tolerance class, this sealed bearing offers high-speed capability, outstanding dimensional stability, and long-term reliability, making it an ideal choice for high-precision spindles and machinery.
S7014 ACB/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| ACB | Universal Matchable bearing with 25° contact angle | Enables flexible mounting arrangements; optimized for combined loads |
| P4A | High precision tolerance class (equivalent to ABEC 7) | Ensures minimal runout and vibration for precision applications |
| DGA | Pre-loaded duplex pair, universal arrangement | Provides immediate stiffness and eliminates internal clearance |
S7014 ACB/P4ADGA Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The duplex pair configuration with 25° contact angle creates a rigid bearing system capable of supporting significant combined radial and axial loads in both directions. The extra light preload ensures optimal stiffness while minimizing friction and heat generation.
Precision Performance: Manufactured to P4A tolerance standards with tight dimensional controls (bore: -0.004mm to 0, OD: -0.004mm to 0), this bearing delivers exceptional running accuracy. The phenolic resin cage provides excellent guidance and stability at high speeds.
High-Speed Capability: With a limiting speed of 28,000 rpm and optimized internal geometry, the bearing maintains stable operation under demanding conditions. The sealed design with factory-applied grease lubrication ensures consistent performance throughout the operating temperature range of -30°C to 110°C.
Maintenance-Free Operation: The integrated sealing system protects against contamination while retaining lubricant, enabling long service life without re-lubrication in many applications.
